Exhibit 99.1

EMAIL TO EMPLOYEES

To All Interline Associates,

I am pleased to share with all of you some very exciting news for our Company.  This morning we issued a press release announcing that Interline Brands, Inc. has signed a definitive agreement to be acquired by affiliates of GS Capital Partners LP (“GS Capital Partners”) and P2 Capital Partners, LLC (“P2 Capital Partners”) for $25.50 per share in cash. GS Capital Partners is one of the world’s leading private equity investors and the fund through which Goldman Sachs invests capital on behalf of its clients and itself in large, privately negotiated transactions.  P2 Capital Partners, a shareholder of Interline, is a leading investment firm that applies a private equity approach to investing in the public market.

As a result of your hard work and our continued investment in the business, we have built a lot of momentum throughout 2011 and this year.  We remain very optimistic about the prospects of our Company and our current business plan, and we plan to continue to execute on our strategy.  As you already know, we have a terrific company with strong financial results, a great team, market-leading brands and a world-class distribution network.  This agreement represents an exciting opportunity with new partners, while allowing us to remain laser-focused on our goals and capabilities.

Importantly, GS Capital Partners and P2 Capital Partners share our vision of Interline’s growth potential and the actions needed to realize such growth.  In addition, as a private company we will have greater freedom to focus on longer-term investments and opportunities, while continuing to provide you, our teammates, with rewarding careers, excellent benefits and challenging roles.

While this announcement is exciting, it is only the first step in a lengthy process.  Our Board of Directors has unanimously approved this agreement, and we will now enter what is known as a “go-shop” period during which the Board will solicit alternative proposals over the next 30 days, in order to confirm that this agreement is the right decision for our shareholders.

The most important thing you can do is to continue performing your roles at the highest level and delivering outstanding value to our customers.  As I’ve said many times before, our employees are this organization’s greatest asset, and with your help, we will continue to provide the same high quality goods and services our customer have come to expect from Interline Brands.

To hear more detail about this exciting development, I invite you listen to a digital recording of my prepared remarks by dialing 1-855-859-2056 or 1-404-537-3406 and referencing conference I.D. number 86203314.  This recording should be available starting at 11:00 a.m. Eastern time and will expire at 11:59 p.m. Eastern time on May 31, 2012.

We will continue to provide you with updates on the progress of this transaction, as appropriate, and we ask that you contact your manager if you have any questions.  We have also attached some additional information to help answer some of your questions.

As your CEO, I would like to personally thank you for your continued dedication and hard work.  With your help and support, I look forward to a bright future together.

Sincerely,

Michael Grebe

Chairman and Chief Executive Officer
